Law of Multiple Proportions is that when one element combines with a second element to form two or more different compounds, the weight of one of the element which combine with a constant weight of the other, bear a simple ratio to one other.
The Law of Chemical Combination are as follow: (1) The law of conservation of mass. (2) The law of constant or definite proportions. (3) The law of multiple proportions. (4) The law of reciprocal proportion. (5) The law of gaseous volumes.
